Aberlour A’Bunadh – batch 49

Welcome to one of the best known “sherry bombs” – the Aberlour A’bunadh.

From Gaelic, a’bunadh means ‘(of) the origin”, or “the original”, and is meant to honour an earlier style of whisky making at the speyside distillery Aberlour. Pronounciations are always tricky, but the full name of the distillery and whisky would best be pronounced a-ber-LAU-er ah-BOON-ar.

A’bunadh is a cask-strength single malt, produced in limited run batches. For this reason, each batch has a batch number instead of an age statement, with a variable absolute alcohol by volume (typically, ~59-61% ABV). They make several batches a year.

One of the distinctive features of A’bunadh is the exclusive aging in first-fill Spanish oak Oloroso sherry butts. I’ve seen various estimates online, but it appears that each batch is blended from barrels in the 5-25 year old range. Note that while it is widely believed that there is significant batch-to-batch variability (see below), all would qualify as “sherry bombs”, given the exclusive sherry cask aging.

Given the heavy focus on statistics on this blog site, an interesting question is how best to incorporate the batch-based A’bunadh into the meta-critic whisky database?

Given the large number of batches each year – and the corresponding limited number of reviews for each batch – I initially considered simply collecting scores on a per reviewer basis. So, if a reviewer had sampled multiple batches, I would average their scores across those batches (thus producing a single score per reviewer). As always, I would limit batches to those produced in the last ~5 years or (i.e., from batch ~30 and on up), to be consistent with other whiskies in the database.

Now, you could argue that this method would obscure any underlying pattern in natural batch variation. So I decided to first look at reviewers who had scored multiple batches. Surprisingly, I found very low variation across batches from each of these reviewers. Indeed, for reviewers who had scored a good number of A’bunadh batches (n>6), the standard deviations of their scores varied from ~0.10 up to ~0.25, per reviewer. Thus, despite the commonly held view that individual batches of A’bunadh are highly variable, you don’t see much variance in scores among at experienced reviewers. As such, I think it is worthwhile considering what an average across batches looks like, for all reviewers:

Aberlour A’Bunadh (all batches): 9.02 ± 0.21 on 16 reviewers

Clearly, this is a popular whisky, with a well above-average meta-critic score for its class (cluster A, of the ABC super-cluster). It also has a below-average standard deviation across reviewers, compared to other whiskies in my database.

But that isn’t the end of the story – you need to consider all patterns in the data. Specifically, while reviewers generally look favourably on all batches of A’bunadh, they do have their relative preferences. And more importantly, there seems to be some consistency in the relative rankings across reviewers.

To explore what I mean by that, let’s take a look at all A’bunadh batches scored individually, across all reviewers. For this, I am only reporting below modern batches for which I have at least 4 individual reviews.

Keeping in mind the relatively low number of reviews, you can see that almost all of these fit quite well within the overall mean and SD of the all-batch data presented earlier (which is, by definition, based on the largest number of reviewers). But one batch really stands out for me, as it is a full SD unit from the overall mean – batch 49.

As you can see above, batch 49 gets the highest score (9.24) and lowest standard deviation (0.08) of any specific batch in my database. More than that, when looking over percentile rankings for the five reviewers who have tried multiple batches including this one, batch 49 is consistently their highest ranked A’bunadh version.

Below is what I find in the glass for this batch. Again, expect some variability from batch to batch, but all should fall within a general flavour range:

Nose: Big and bold sherry flavours, with raisins, figs and chocolate most prominent. Some other dark fruits are below the surface (e.g. cherry), but you will need some water to bring them out. Neat, there is a fair amount of alcohol burn here (i.e. it singes the nose hairs if you inhale too deeply). Water helps on this front as well.

Palate: Sweet and delicious, with more of the fruits showing up now – especially cherry and raspberry. Also orange marmalade and dark chocolate. Mouthfeel is thick and oily, with a syrupy nature. Just a touch nutty as well. With water, it opens up further, with rich notes of Christmas cake, fig pudding, and creamy milk chocolate. Becomes like Christmas in glass, including those chocolate orange candies.

Finish: Long. While there is an initial alcohol burn (subdued with water), a fruity sweetness persists for awhile. Unfortunately, a bit of bitterness creeps in over time (almonds? coffee?) – which is the one thing holding this expression back a bit for me.

General consensus on the subject of water is hard to come by here, as it seems that many prefer drinking it neat, at cask strength. Personally, this is one where I think water greatly improves the experience. And not just a few drops – a significant amount of water is actually better. Taking it down to ~50% ABV was my personal sweet spot, taming the burn and bringing out more of the fruit flavours. There were rapidly diminishing returns beyond that though – by ~45% the whisky definitely felt flooded. You will want to experiment to see what works best for you.

I am glad I was able to pick up a bottle of batch 49 while it was available, and am now on the hunt for samples of other batches to compare. Batch 49 is certainly very flavourful, with no hints of the sulphur that sometimes mars some sherry cask batches. It is an outstanding value for $95 CAD at the LCBO.

To get the experience of those who have sampled many batches, I suggest you check out André, Patrick and RV at QuebecWhisky.com, Serge and WhiskyFun.com, or Ruben at WhiskyNotes.be. Given the generally high scores, it is hard to find a truly negative review of any A’bunadh batch. When it does happen, it is usually due to the detection of sulphur compounds (see for example Oliver’s experience of batch 45 at Dramming.com).

If you can find it, the Aberlour A’bunadh is a strong candidate to consider for the “sherry-bomb” corner of your whisky cabinet.
